One of the tricks to sounding 'urgent,' as they like to say (or at least they did when I was in the business) is that you never use the 'm' or 'n' sounds because they sound passive. Instead, you substitute a hard consonant.

DOWWWW is really big in TV news. TV news is immediate, intense and filled with drama and excitement, and it's all happening DOWWWW. The station wants you to know that it's not covering old, stale news - it's covering news (or dews) that's going on DOWWWW.
I guess you could say they're DOWWWWists....
...but I wish you wouldn't.
